Answer:
Organisms that are in existence to day must have evolved from Ancestral species million of years ago.
Natural selection is the main driving mechanisms for evolution of new species.
Explanation:
Genreally organisms produce more
offsprings than they can provide for in a particular environment.
Because of thre limited resources available due to overpopulation, organisms must develop certain characteris or traits to survive.
Offisprings that survived must have inherited these traits from thier parents, while those without these traits will die.
Natural selection must be the mechanism for the selected organisms to withstand selection pressure of limited resources.
This is survival of the fittests by natural selection.
A map that locates genes and markers based on the actual length of the dna sequence is called a physical map. In the physical map <span>molecular biology techniques are used to examine </span>DNA<span> molecules directly in order to construct maps showing the positions of sequence features.</span>

While plants can produce their own energy using the process of photosynthesis, animals (and other organisms that can’t do photosynthesis) must eat to get energy from food molecules. Just like energy can be stored in the chemical bond between the second and third phosphate of an ATP molecule, energy can also be stored in the chemical bonds that make up food molecules. Most of the energy that we use comes from molecules of glucose, a simple sugar.
